Abstract: APPARATUS FOR RUNNERLESS INJECTION - COMPRESSION       MOLDING OF THERMOSETTING MATERIALS                     ABSTRACT     The apparatus of the present invention includes a stationary assembly and a movable assembly.  The station-ary assembly is comprised of a stationary platen which has a heat plate, a temperature-controlled sprue bushing and a mold face positioned thereon.  The movable assembly is comprised of a movable platen which has a heat plate mounted thereon and a mold face, corresponding to, and adapted to be aligned with, the mold face on the sta-tionary assembly to form a partially open mold cavity.        Means are provided to feed a supply of thermosetting molding material through the sprue bushing into the partially open mold cavity.  Means are provided to com-pletely close the mold cavity and place the apparatus in a compression stage.  In the injection and in the compression stages, the discharge end of the sprue bushing is in direct feed relationship with the mold cavity, allowing flow of molding material from the sprue bushing into the mold cavity in the injection stage and flow of molding material from the mold cavity into the sprue bushing in the compression stage.  Means are also provided for the subsequent retraction of the movable assembly to allow removal of a molded article and access to the mold area.

Abstract: ABSTRACT OF THE DISCLOSURE   The test device is based on the detection of the current in  a  two-wire line, such as a telephone loop, and enables to remote locate a short circuit or analogous. The invention deals with sensing the current at a predetermined line emplacement -upon adding simple switch means- also to control switching of the line, such as a working line, with another two-wire line, such as a spare line, or to select one of two loads terminating the line. The test device is inserted in series-connection on one of the line wires. Its ohmic value is constant in a low current range when the in-line current is less than a predetermined current value, and increases sharply to a higher ohmic value in a high current range when the in-line current is greater than the predetermined  current value. Preferably the  test device comprises a relay having an operate coil and a resting contact which are series-connected between the terminals of the test device, and a resistor parallel-connected with said contact.

Abstract: A Container for Receiving and Safely Storing Radioactive Materials and Method for Tightly Sealing the Same Abstract The invention is directed to a container for receiving and safely storing radioactive or other materials damaging to living organisms, especially such materials as vitrified radioactive fission products or irradiated nuclear reactor fuel elements.  The container includes a vessel and a sealing cover.  The vessel has a circular opening at one of its ends for receiving the materials to be stored therein, and a sealing cover is seated in this opening to tightly seal the container.  In order to obtain a container of the kind which has the required high impermeability to gas, the open end of the inner bore of the vessel is widened to define a conical surface.  A sealing cover is pressed into the vessel at this conical surface.  The sealing cover has a peripheral surface which converges toward the interior of the vessel and which has a taper corresponding to that of the conical surface of the vessel.  The vessel wall and sealing cover are welded together by means of a fused-mass joint extending around the entire periphery of the cover.    By means of the conical configuration of the upper end portion of the vessel and of the sealing cover, a considerably improved seal between the vessel wall and the sealing cover is obtained.  A method for sealing the container is also disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE         A cooling and heating device having a cooling cycle circuit and a heating cycle circuit with a refrigerant heater for heating refrigerant includes a cooling circuit extending from a compressor through an outdoor heat exchanger, a resistance element (capillary) and an indoor heat exchanger to the suction inlet side of the compressor; and a heating circuit extending from between  the discharge outlet side of the compressor and the outdoor heat exchanger directly through the indoor heat exchanger and the refriger-ant heater to the suction inlet side of the compressor. In the heating operation, the high temperature refrigerant from the compressor, which is heated by the refrigerant heater, flows in the indoor heat exchanger in a direction opposite to that in which the refrigerant flows in the cooling operation, so that the refrigerant radiates heat through the indoor heat exchanger, and the refrigerant phases on either side of the indoor heat exchanger are the same for either cooling or heating.

Abstract: CONDUCTIVE COATINGS FOR ELECTRET DEVICES          Abstract of the Disclosure Electret transducers, for example microphones, have a backplate which is metallized on one surface, the metallized surface forming one side of a capacitor.  A frame sits on the metallized tape to hold the tape taut over the backplate.  Metal connections are made to the backplate and frame to complete the circuit.  The metallization is conventionally formed by vapour deposition of aluminum.  This is a lengthy and relatively expensive process. Also the metallization can give rise to galvanic problems.  The invention prints a pattern of conductive ink on the various parts. Good contact is obtained, galvanic action avoided and a reduction in manufacturing costs occurs.

Abstract: Abstract Narrow Bore Microparticle Column Packing Process And Product A process for packing narrow bore chromatographic columns and the resulting product are provided.  A flexible column, preferably of fused silica, of inner diameter less than 500 µ m is selected.  A slurry is formed in a reservoir from a mobile solvent and par-ticles of specified diameter.  For liquid chromato-graphy the particle size ranges from 3 µ m to 10 µ m; for gas chromatography the particle size ranges from 3 µ m to 100 µ m.  An end restriction is placed in the end of the column to permit the flow of mobile solvent and to restrict the passage of particles out the end of the column.  The reservoir is attached to the column and the slurry is flowed under pressure into the column.          A two-step pressure sequence is used to first set up the bed of particles and then to compress the bed.          First, an initial pressure is maintained for an initial period, preferably less than 10 minutes.          Next, the pressure is raised from the initial pressure to a maximum pressure and is maintained at the maximum pressure for a second period.  The product in either case is a stable, loose packed column having a high plate number per unit length.

Abstract: ABSTRACT OF THE DISCLOSURE:           The present invention relates to a synergic growth-promoting feed supplement composition for farm animals which contains 2-formylquinoxaline-1,4-dioxide cyanoacetylhydrazone, which has the generic designation cyadox, in combination with antibiotics and/or sulfonamides.  These substances were sur-prisingly found to enhance synergically the favorable effect of cyadox on the animal growth promotion and feed utilisation as well as on the suppression of pathogenic microorganisms.          The feed supplement composition according to the invention is advantageously used in the form of additives to feed-stuffs and feed mixtures for farm animals such as, e.g., pigs, calves and poultry.  In comparison with cyadox alone, the composition ensures substantially more efficient increase in live-weight gains, suppression of microbial infections, improvement of the health of animals and reduction of losses by early mortality;  especially remarkable effects are obtained by the use of the composition and of supplemented feed compris-ing same in large-scale breeding conditions.
